cfgadm:::Device being used by VxVM

root@abc>/> cfgadm -c unconfigure c1::dsk/c1t0d0
cfgadm: Component system is busy, try again: failed to offline: /devices/ssm@0,0/pci@1c,700000/pci@1/SUNW,isptwo@4/sd@0,0

/dev/dsk/c1t0d0s2   Device being used by VxVM

“cfgadm unconfigure” command fails here.

The way to resolve this is to disable the disks path from DMP control. Since there is only one path to this disk, the “-f” (for force) option needs to be used:

root@abc>/> vxdmpadm -f disable path=c1t0d0s2

root@abc>/> vxdmpadm getsubpaths ctlr=c1
NAME         STATE[A]   PATH-TYPE[M] DMPNODENAME  ENCLR-TYPE   ENCLR-NAME   ATTRS
================================================================================
c1t0d0s2     DISABLED     -          c1t0d0s2     Disk         Disk           -
c1t6d0s2     ENABLED(A)   -          c1t6d0s2     Disk         Disk           -

You can see the path now disabled from DMP.

root@abc>/> cfgadm -c unconfigure c1::dsk/c1t0d0

cfgadm goes through fine.

root@abc>/>

The cfgadm unconfigure command fails with "Device being used by VxVM".

Problem

The cfgadm unconfigure command fails with "Device being used by VxVM".

Solution

While trying to remove a device from the OS with cfgadm unconfigure the following error occurs.

PROBLEM:
# cfgadm -f -c unconfigure c3::dsk/c3t2d0
cfgadm: Component system is busy, try again: failed to offline:
Resource Information
------------------ -------------------------
/dev/dsk/c3t2d0s2 Device being used by VxVM

Note the Volume Manager daemon is running:
# vxdctl mode
mode: enabled

The vxdisk list command shows the device is not initialized, but does have a valid label.
# vxdisk list
DEVICE TYPE DISK GROUP STATUS
c3t0d0s2 auto:none - - online invalid
c3t1d0s2 auto:none - - online invalid
c3t2d0s2 auto:none - - online invalid


SOLUTION:
If VCS is running, freeze all servicegroup's that contain a diskgroup first.
# vxdctl stop
# cfgadm -f -c unconfigure c3::dsk/c3t2d0
# vxconfigd -x syslog


Notice the c3t3d0 device is gone once vxconfigd rebuilt the dmpnodes from the configured OS devices.
# vxdisk list
DEVICE TYPE DISK GROUP STATUS
c3t0d0s2 auto:none - - online invalid
c3t1d0s2 auto:none - - online invalid

Now a physical disk removal/replacement is possible.
